Letters Patent N o. 107,313, dated September 13, 1870.

IMPROVEMENT IN MECHANISM FOR OPERATING THE PICKERS OF LOOMS.

The Schedule' referred to in these Letters Patent and making part of thesame To all whom 't'tvma'y concern Be it known that we, ELIAS A.WAREIIAM and WILLIAM H. WAeGoNnIt, of Kirkville, in the county ofWapello and State `of Iowa, have invented a new and useful Improvementin Hand-Looms; and we do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had tothe'accompanying drawing forming part of this specification.

My invention relates toloolns, and consists of .an improvement inconnection with the picker-staff, which will be hereinafter described inconnection with all that is necessary to a full understanding thereof,and then clearly specified in the claim.

Figure 1 represents a front view ot' our improved` loon., partly inelevation and partly in section.

Figure 2 represents a sectional elevation, taken on the line x :e ot'ig.l.

Figure 3 is a plan view of one of the shuttle-boxes; and

Figure 4 represents, in front and side elevations, anl arrangement ofcams for producing cloth twille-d on b'oth sides, suoli as we propose tousc in substitution of those represented in the machine, and to adaptfor being readily so changed.

Similar letters 'of reference indicate eorrespomling parts.

A represents the race-beam of the lay, and

B, the sword-arm, arranged in the usual way.

Gis the picker-stati", arranged at the center, and connected by cords Dto the pickers E, so as to operate b oth. y

This stati' is pivoted at F to a suitable support 1"*- ing up from theii'ame, and is considerably enlarged around the pivot to support'thcpins G and the cam*- shaped project-ion H, to be acted on by thedoublehooked and pointed end I ot' a bar, K, connected at L to theIace-beam, so that, by the movement of the said beam back and forth, thehooked end of the said plate has a slight rising andfalling movementupon the enlarged part of the picker-stati, between the pins and againstthe cani projection acting alternately on each side ofthe said camprojection, and against the pins.

having been Inoved last to the right, whereby the point c of the camprojection is moved to the left, so that when the point I4 Inoves downagain at the forward movement of the lay it will lbe carried, by itspoint acting on the right side of the point a of the cam, to the right,so as to engage the hooleb under the right-handv pin G, whereby, whenthe lay is moved back, the npwardmovement ot' the bar K will throw ofthe bars X, extending from the heddle-fi'ame to In the drawing, iig. 1,the stati" is represented ,as

the staff C over to the left, and, on the next downward movement of thesaid 4bar K, the pointed end will be carried down the left side of thepoint a of the The cam-shaft M is provided with a hooked wheel,v

N, having as manyhooks as there are cams, and this wheel is acted uponby a pawl, O, connected to the Arear side of the lay-beam, and arrangedto move forward on the said wheel whenv the lay moves back to engage bya hook or pin with one of the hooks of the ,said wheel N -for turning itforward when the lay moves forward.

To this cam-shaft, which I propose to arrange in its hearings, so as tobe readily removed for the substitution of other shafts with otherarrangements of cams, for instance, that represented in iig. 4, I coupleon, in'any preferred way, a short extension, 1, running to the outsideof the frame, where it is provided with a crank, Q, and connecting-rodor pawl It, adjustably connected to the said crank by a slotted barmoving the wrist-pin back and forth.

' This pawl engages, at the other end, with the ratchet-wheel S, 'on thecloth-beam, by which the lat ter is moved for taking up the cloth.

For the purpose of producing a uniform action ot' the cams on thehcddle-frames U, which work in vertical guides V, and must necessarilystand each in a dilierent plane relatively to the plane of the axis ofthe cam-shaft,'I provide shoes, XV, at the lower ends the cams.

These slices are of uniform length, and all arranged in the samerelation tothe axis of the cam-shaft, whereby the rise and fall of eachheddle-frame will occur in the same order in respect to the movement ofthe cams or other parts of the loom.

The tension of the warp-beam Y is produced by a friction-brake,consisting of a lever, grooved at one end to tit the periphery ot'afriction-rim, Z, on the roll,` and connected by a pivot-joint, Z2, tothe frame, the other end being provided with a temper-screw, Z, passingthrough it, and screwing down upon said end to increase the friction onthe rim Z, or to release the same by unscrewing to allow the brake torise.

Below the breast-beam we have arranged a wheel, A', with pointed teeth,to press against the cloth as it Inoves from the breast-beam to thetake-up roll, so as to be turned by the cloth. v

The outer end of the shaft of this wheel is provided i with a singletooth, B2, gearing with Ia large toothed wheel, C', which may have agreater or lesser number of teeth, anda scale graduated to the teeth andthe wheel A', in any preferred way, so that the number of yards woundupon the roll can be ascertained at any time from the said scale.

The shuttle-binder consists of a round block, b, iig. 3, let into arecess in the side of the shuttle-box, and connected to a spring, l1, sosecured inthe said side that the blockwill he pressed through theopening of the recess into 'the shuttle-box snficently to press theshuttle when received into the box against the opposite side. Y

These blocks are slotted at b, and pins are arranged in the box to riseup through the slots, so as to control thc blocks against the tendencyof the shuttles to force'the blocks in the direction ot' their movementeither way, while allowing them to oscillatcifreely to and from therace. x

Having thus described our mventionl' n Te claim as new and desire Ytosecure by Letters Patent- VVit-nesses: WM. H. WAGGONER.
